Hi Katelyn,
Entering “no” in the User Scalable field seems to be working in the iOS device on our end. Can you attach a copy of your RP file? If you’re unable to share the specific RP file, feel free to recreate the issue in a new one (via “File > New”), enter “no” in the User Scalable field at “Publish > Generate HTML Files > Mobile/Device > User Scalable”, and attach it here. If possible, please also include a link to your hosted prototype or publish it to Axure Share (“Publish > Publish to Axure Share”) and provide the generated link. Thank you!
